I don't know if there is linking at the tour level.
Mark Howard with JC Outdoors, Rob Lay or several others on here can probably answer.
I know that if you want to fish all of the Tour events and pay our deposits for all then you are pretty much guaranteed to get in.
If you are just doing one event, you should be ok as long as you get registered pretty quick.
The people who answer and register you are very helpful and will be glad to answer any questions that you may have.
